Compatable 5.1 Cinema Systems?

I am looking to invest on surround sound for my ps3.
However the only surround sound system which i can confirm that works is the Logitech Z-5500, which is £200.
Just wondering if there are many other systems that will give me true surround sound which is less costly...
thanx

Im not sure about that one,why dont you just go for an AV system,thay have multiple inputs/outputs and a FM/AM Tuner built in.This one looks cool,it dosnt have HD audio but is powerful and has lots of cool features.

To get Dolby TrueHD you can not use optical or coaxial as it doesn't have enough bandwidth (1536kbs limit). You will need to send it to a compatible receiver via HDMI v1.3 (10.2gbs limit). Another option would be to let the player decode it to PCM and send it to your receiver via the analog outputs... Obviously not an option for the PS3 as it lacks the multi channel analog outputs.

The PS3 can output Dolby TrueHD but only via it's HDMI v1.3 connection. You can send it digitally via HDMI or the PS3 can decode the TrueHD track and send it as PCM via the HDMI cable (this is useful for receivers that have HDMI v1.3 but don't have the Dolby TrueHD decoder).

These HDMI v1.3, Dolby TrueHD, DTS-HD AV receivers are very expensive, so if you want 5.1 sound then you may be better settling for a regular Dolby/DTS set-up.
